After serving 28 years in the Marine Corps I was dealing with some serious back pain that had been plaguing me for years. After several years of mediocre at best physical training via the military I could not get any resolve without medication. Fast forward to my retirement and I was referred to The Function Chiropractic via the VA hospital. He assessed my situation and created a functional plan that has resulted in relief that I never thought was attainable. The Kinetic Impact team will go above and beyond to ensure the problem is identified and an attainable functional plan is created to address the issue. I highly recommend The Function's team as they care about their patients and will not rest until a reasonable resolution is provided.

The Function is an amazing place to go to if you’re looking to improve yourself. These guys have backgrounds in kinesiology, chiropractics, and strength and agility training. They provide a great mix of all of these when they work on you. I personally starting seeing them last week due to some pain in my right shoulder and tightness in my lower back. Now after two sessions I already feel massive improvement in both of those areas. These guys are fantastic and know exactly what they are doing. Would highly recommend!

Thank you Doctor. I love that working out was incorporated into my treatment plan. It's very exciting to see and feel the change in my body. If you really want to help yourself get healthy, The Function Chiro is a great place to start your journey.

Dr. Cedric is just an amazing all around person and thee best chiropractor in the Bay Area. I myself have received exceptional care and now I am taking my 1yr old daughter to receive the same compassionate and professional care I’ve come to experience from Dr. Cedric and his wonderful staff! We plan to continue our care and hope that you make the healthy decision for you and your family!

Thank you Dr. Cedric for a wonderful and much needed adjustment! My body’s at 100% again and most importantly can breathe. Your office is welcoming, clean and very comfortable. You have a very lively and energetic team. I can’t wait to be back again!

Dr. Vinson created a very relaxed amd welcoming environment. It was my first time getting adjusted and he took time to educate as he worked. He made the whole process feel easy and accessible. I will definitely be coming back for future appointments. Thank you for a great experience!

Doesn't matter if you're looking for a quick adjustment, a new doctor, or just trying chiropractic because surgery is not an option, this is a great office. Dr. Cedric is truly a master of his craft with empathy. Highly recommend trying out any of his locations, you'll be back for more.

One of the best full body adjustments I have had in a while. I went in for my TMJ and Dr. Cedric adjusted all of my limbs as well. Very friendly, welcoming and clean environment. Highly recommend!

Melissa is amazing! I love her authenticity and warm personality 😃 She has a very thorough and specific approach to chiropractic care which allows her to speed up the healing process of her patients. I would definitely recommend this future doc to my friends and family!

Melissa is a genuine, knowledgeable person who is sure to help with your healthcare needs! She's an amazing person and chiropractic intern! I highly recommend her!!

Matt D.

It was my first time getting adjusted, so I was a little nervous, but Dr. Vinson made me feel really comfortable every step of the way! He also educated me about the process and made sure I knew what to expect during different parts of the adjustment. He took his time when he adjusted my neck, and explained what he noticed that could be connected to my frequent migraines. I’m grateful that it was a comfortable and gentle experience! Thank you, The Function!

The Function Chiropractic is off the charts good. I've seen a few chiropractors before, but never stuck with them long(er) term because I didn't really feel like I was getting any better. I have a few sports injuries from working out/heavy lifting and was in a car accident ten years ago and the combination of these includes a lot of discomfort in my upper back and many imbalances overall. I've been seeing Dr. Vinson for a few months now and feel SO much better than when I first started coming to see him. The pain in my back is virtually non-existent and a long term abductor problem is substantially better than it was when I first started seeing him and continues to get better each time! The imbalances that I also felt previously while working out are virtually gone as well (some I didn't even know I had!) I do continue to have new problems pop up here and there and Dr. Vinson is amazing at addressing them each time I see him. I also appreciate that they don't rely on fancy gadgets like many chiropractors seem to do. The knowledge Dr. Vinson (and I'm sure the other chiropractors) have about the body far surpasses any of the fancy gadgets from other offices. Highly recommend to anyone looking for a great chiropractor in the area!

Dr. Melissa is at the top of her game. This woman deserves a raise. She is the first person who was able to crack my mid back in over two decades. The rest of her amazing team was able to eliminate my lower back and neck pain over the summer. Their service is second to none. No surgery necessary. Good looking out.
